摘要

近年來，平地之土地開發已趨飽和，所以土地開發之工作有朝向新生地發展趨勢，諸如基隆河截彎取直及麥寮六輕工業區等。而新生地因地質不佳，首重區域內排水問題，本文旨在介紹排水帶排水原理、使用之材料及機具，並舉出在基隆河截彎取直工地之垂直打設排水帶工法實例加以說明，以增加各界對該工法之認識與瞭解。

In Taiwan, most of land development projects are towards to planning and developing wet land near the shore, because the plain land development is out of limit. The key problem of the wet land development is how to accelerate settlement by the best time-saving and high-quality drainage method. This paper tries to introduce the Vertical Drainage Method and explain the principle of this method, the materials and equipment of this method. At last, it will introduce the actual application for vertical drainage method in Keelung-River Relocation and Reclamation Project.
